I think the TT250 will be your best bet from a warranty angle. If you are going to Shiprock, I would suggest Canyon de Chelly (Chelly is pronounced 'shay'). I always found it to be like the Grand Canyon, but much more intimate. I was about an hour from there when I lived and worked on the Navajo Nation, and went often. In fact, I went to see the Grand Canyon for the first time after seeing Canyon de Chelly, and was kind of let down, lol. Anyway, definitely let us know when you leave, and maybe some members along the way can meet up with you!
